Turn up in nomad's tent for dairy produce (6)
I believe the answer is:
yogurt
'dairy produce' is the definition.
(I've seen this before)
'turn up in nomad's tent' is the wordplay.
'turn' becomes 'go' (a person's move in a board game).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'in' is an insertion indicator.
'nomad's tent' becomes 'yurt' (I've seen this in another clue).
'go' back-to-front is 'og'.
'og' placed into 'yurt' is 'YOGURT'.
'for' acts as a link.
(Other definitions for yogurt that I've seen before include "Dairy product made from curdled milk" , "Dairy produce" , "Food made from milk thickened with bacteria" , "Milk-food" , "Fermented milk product" .)
